Hi! Thank You for your query. It is important to realize that "treating" stretch marks is done to improve their appearance in a way that is satisfying to patients. Since a stretch mark is like a scar, with thin, attenuated abnormal skin, it can not be erased and made to appear like normal skin. But the treatment does thicken the skin, make the shininess diminish, make the width narrower, creates a more healthy skin structure by repopulating the stretch mark with collagen and elastic fibers and so makes the stretch-mark containing skin look more normal. There is a very high patient satisfaction rate with fractional laser treatment. One should plan on at least 4-6 treatments at 4-6 weeks intervals and be patient while the changes are occurring. They generally do not require bed rest and are opd based procedures.
